CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 51 1,260, dated December 19, 1893. Application filed June 29, 1893. Serial No. 479,166. (No model.)

To aZZ whom it may concern.-

Be it known that we, ISAIAH F. YOOKEY, JOHN D. YOCKEY, and CHRISTOPHER O. YOCKEY, citizens of the United States, residing at Chanute, in the county of Neosho and State of Kansas, have invented a new and useful Check Row Attachment for Corn- Planters, of which the following is a specification.

Our invention relates to improvements in check-row planters of that class which do not employ a wire; and the objects in view are to provide a cheap and simple planter adapted to accurately drop corn in rows and indi cate the same upon the soil; to provide a convenient mechanism between the axle and seed slide for operating the latter; to adapt the wheels to pass over obstructions and yield thereto thereby avoiding breaking the axle or deflecting the machine from a straight course; and to provide for a convenient and adjustable support of the seed-boxes or hopers.

With these and other objects in view the invention consists in certain features of construction hereinafter specified and particularly pointed out in the claims.

Referring to the drawingsz-Figure 1 is a rear perspective view of a planter embodying our invention. Fig. 2 is a front elevation. Fig. 3 is a top plan view. Fig. 4 is a longitudinal sectional view. Fig. 5 is a detail in vertical section of one end of the axle and the beam in which it is journaled. Fig. 6 is an end elevation of the machine.

Like numerals of reference indicate like parts in all the figures of the drawings.

The main beam 1 of the machine is transversely disposed, and under it is secured the longitudinal beams 2 located at the ends of the beam 1. Short longitudinal beams or arms 3, which correspond with the longitudinal beams 2 extend forwardly and in line therewith, and the beams 2 and 3 are provided with bearings,those of the beams 2 being open upon their upper sides. An axle 4: is mounted in the bearings of the beams 3, and short stub axles 5 are mounted in the bearings of the beams 2, the adjacent ends of said axles being connected by means of gimbahjoints 6, whereby the axles 5 may have an up and down motion. Stirrups 7 extend from the beams 2 over the axles 5 and are connected neartheir upper portions by tic-plates 8 from which studs 9 depend. Upon these studs coiled springs 10 are arranged, the lower ends of said springs resting upon hearing blocks 11 whiclrbear upon the axles 5. From this it will be seen that if at any time one of the ground-wheels meets with an obstruction the wheel at that side of the machine will rise and yield to the obstruction, thus obviating the transmission of any material shock or wrench to the axle and a disturbance of the mechanism connected with and operated thereby; The stirrups at their lower ends are threaded and nuts 14 are applied thereto so that by running the nuts up upon the terminals of the stirrups, the tension of the springs may be increased or diminished.

Bearing-blocks 15-are located upon the under sides of the beams 2 below the beam 1, the said bearing blocks being secured'in, position by means of eye-bolts 16 passed therethrough and through the beams 2. The bearing blocks are arranged in pairs located 1ongitudinally opposite each other, and each pair supports and forms an inverted bearing fora U-shaped hanger 17. The terminals of these hangers are slottedas at 18, and secured to the same through the medium of set-screws 19 opposite depending hoppers 20 are supported. These hoppers are of the ordinary construction and are connected by transverse bars 21. A slide bar 22 is mounted for reciprocation above the hoppers. Thus it will be seen thatthe hoppers may be raised and lowered as may be desired.

Upon the axle 4 at one side of the center thereof there is rigidly mounted a beveled gear 23, which receives rotary motion from the axle and transmits the same to a short crank-shaft 24 which is jourualed in a hearing 25 mounted under the beam 1, through the medium of a beveled gear 26 mounted upon the rear end of said crank-shaft: The crank 27 at the front end of this shaft is connected loosely with one end of a connectingrod 28, the same having its free end bifurcated as at 29 and loosely receiving the lower end of a vibratory lever 30, which is located between the two hoppers and is pivoted as at 31 to a bearing block. The upperend of this vibratory lever is transversely slotted as at 32 and a pin 33 passes through the same and through the bifurcations of the connectingrod so that as the crank-shaftis revolved the connecting-rod is oscillated or reciprocated, and at the end of each movement contacts with the end of the slot in the vibratory bar, thus throwing the latter in alternate directions, and it being loosely connected with the slide-bar reciprocates the latter which operates in the usual manner to discharge the seed from the hoppers. The outer ends of the short axles form bearings for groundwheels 34, and the rims of the latter are provided with marking-blocks35, which mark the soil at the dropping of each seed, so that the operation may be observed and the point of dropping located by the operator when seated upon the machine.

The machine is provided with the usual furrow-opening shovels 36, seed-tubes 37, and the covering-shovels 38, attached to standards 38 all of which being of the usual construction require no special description.

The draft-tongue is connected to the central one of the series of longitudinalbeams 3.

We do not limit our invention to the precise details of construction herein shown and described, but hold that we may vary the same to any degree and extent within the knowledge of the skilled mechanic, without departing from the spirit of our invention or sacrificing any of the advantages thereof.

From the foregoing description, in connection with the accompanying drawings, it will be seen that we have provided a machine of very simple construction, one in which the seed-slide is positively operated at regular intervals by the rotations of the axle as caused by the ground-wheels; that either one of the ground-wheels is free to yield and pass over obstructions that are often to be met with in fields undergoing the operation of planting without injury to the other wheel or to the axle.

Having described our invention, what we claim is-- 1. In a planter, the combination with a framework having a transversely aligning series of bearings, and an axle occupying the intermediate bearing, of adjustable stirrups arranged over the outer bearings, springs depending from the stirrups, bearing-blocks sup ported by the springs, short axles mounted in the bearing-blocks and the outer bearings,

framework, of opposite U-shaped standards depending from the sides of the frame and having their terminals provided with slots, hoppers arranged between the standards, and bolts passing through the slots in the hoppers whereby the latter are adjustable, substantially as specified.

3. In a planter, the combination with the opposite beams comprised in the framework, blocks arranged under the beams in pairs, eye-bolts located in the blocks and extending through the beams, of U shaped hangers loosely journaled in the eye-bolts and having their downwardly disposed terminals slotted, and intermediate hoppers arranged between the standards and provided with set-screws passing through the slots thereof, substantially as specified.

.4. In a planter, the combination with a transverse beam, forwardly extending beams mounted thereon, an axle journaled in said forwardly extending beams, ground-wheels arranged upon the axle, and a beveled gear arranged upon the axle, of ashort crank-shaft journaled in the transverse beam at a right angle to the axle, a beveled gear thereon engaging the gear of the axle and bifurcated at its'free end, a vibratory lever mounted on the transverse beam and having its upper slotted end embraced by the bifurcations of the connecting rod, a pin passing through the bifurcations and through the slot of the vibratory lever, opposite hoppers, and a slide-bar for the hoppers connected with said vibratory levers, substantially as specified.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
